European specialist investors Pymwymic and DTCF back Stenon’s nitrogen and soil organic carbon capabilities, international growth and a new technology platform.
Potsdam, Germany, July 1, 2026 –Stenon, the German AgTech company enabling efficient and sustainable nutrient management through real-time soil analysis, today announced €18 million in Series B financing. The funding will accelerate new product development and expansion in markets where Stenon already has commercial operations, with a clear focus on real-time nitrogen management and soil organic carbon (SOC).
The round was led by Pymwymic, a pioneering European impact investor focused on food and agriculture. The DeepTech & Climate Fonds (DTCF) also joined as a new investor, bringing specialist experience in scaling capital-intensive European deep-tech companies. Existing investors Atlantic, Oyster Bay, Founders Fund, TIME Ventures (Marc Benioff’s investment firm) and Bernd Hoffmann (former VP at AGCO and Claas KGaA) also participated.

Nitrogen management at a critical moment
Nitrogen supply and pricing have returned to the center of farm economics. Renewed market volatility is increasing pressure on farmers and agribusinesses to improve nitrogen-use efficiency without compromising yields. In April 2026, overall nitrogen fertilizer prices in the European Union were 71% above the 2024 average, according to the European Commission.
Stenon addresses this need by measuring plant-available nitrogen (Nmin) directly in the field and combining it with SOC and other soil parameters. The company’s N + SOC approach links immediate agronomic action with long-term soil management: Nmin data supports the amount and timing of fertilizer applications, while SOC provides a baseline for soil condition, productivity and carbon-related programs.
“Farmers cannot control global nitrogen supply or prices, but they can control how precisely each kilogram is used. That is why nitrogen management is Stenon’s core competence. By combining real-time plant-available nitrogen measurements with SOC insights, we help customers make better immediate fertilizer decisions and build a longer-term view of soil productivity. This financing allows us to scale that capability in the markets where it is needed most.”
Niels Grabbert, Founder and CEO of Stenon
Stenon’s FarmLab combines proprietary optical and electrical sensor technology, artificial intelligence, agronomic models and cloud software to generate real-time soil data directly in the field. Instead of waiting for laboratory results, users can measure more frequently, map field variability and optimize fertiliser applications based on current conditions.
What sets Stenon apart is its ability to measure plant-available nitrogen directly in the field, the data point farmers need to make immediate fertiliser decisions. Multi-year, multi-country customer use cases already show clear farmer ROI: 20-40% nitrogen fertiliser savings and 2-8% yield increases across crops including corn, beans, cotton, sugarcane, coffee, grains, and vegetables. The platform serves input retailers, agricultural groups, machinery dealers, agricultural consultants and food producers, and has already been deployed across several million customer acres.
“Stenon sits at the rare intersection where improving soil health and strengthening farm economics go hand in hand. Its technology empowers farmers with better data, enabling more efficient input use while building the foundation for more productive and resilient soils.”
Rogier Pieterse, Managing Partner of Pymwymic
“Stenon’s groundbreaking technology is unlocking high-resolution real-time understanding of soil fertility, helping farmers optimize their largest input cost. We are thrilled to support Niels and the team as they scale this transformative solution.”
David Friedberg, CEO and Partner of The Production Board
Product development, market expansion and the next technology platform
The Series B financing will be used to:
- Expand commercial and service operations in South America, with Brazil as a core market, as well as Central Asia and selected European countries where Stenon already has commercial activity;
- Strengthen regional agronomic calibration, product localization, and customer support;
- Advance FarmLab’s nitrogen management and SOC measurement capabilities; and
- Most importantly, advance its technology from its proven handheld field sensing system to a machine-integrated, real-time nutrient intelligence system.
Developed in stealth over the past several years, as part of this next phase Stenon is preparing to unveil the next evolution of its technology platform. Built on the solid sensor, data and AI foundations established with the FarmLab, the platform will be announced later in 2026, with further product and commercial announcements to follow.
“FarmLab has proven that high-quality nitrogen and SOC data can be generated directly in the field. The next step is to make this intelligence more continuous, more integrated and more actionable for large-scale agricultural operations. We are building towards a system where nutrient decisions are supported by real-time data at the point where those decisions are actually made.”
Jens Meichsner, CTO of Stenon
Brazil remains a priority market for Stenon. The company is active in key agricultural regions including Goiás, Mato Grosso, Paraná and São Paulo, where fertiliser economics and timely soil data have a direct impact on production margins. Stenon also operates in Central Asia and selected European markets, adapting its models and recommendations to local soils, crops and agronomic practices.
The participation of Pymwymic and DTCF adds two complementary European investment perspectives to Stenon’s shareholder base: deep sector expertise in food and agriculture and long-term capital for deep-tech scaling. Together with the continued support of existing investors, the financing positions Stenon to accelerate international growth while investing further in proprietary sensor technology, agronomic models and its soil data platform.
“Real-time soil data is infrastructure for modern farming, and Stenon has built the foundation to deliver it at scale. Farmers today make million-euro fertilizer decisions based on soil data that is weeks old. Stenon closes that gap directly in the field, backed by a sensor system that is genuinely hard to replicate and a scalable hardware-SaaS model. This is precisely the kind of deep-tech company DTCF invests in, and we are excited to support the team as they grow.”
Dr. Achim Plum, Managing Director at DTCF
